Although many causes of curvilinear renal calcifications have been described, calcified hydrocalycosis mimicking hydatid cyst has not previously been reported. We report a case of hydrocalycosis which was appeared as a curvilinear calcified cystic lesion resulted from staghorn calculus associated with xanthogranolomatous pyelonephritis (XGPN) on intravenous pyelography (IVU) and computed tomography (CT).
A 60-year-old man presented with impotence ultrasonography demonstrated bilateral irregular hypoechoic infiltration of testes and normal epididymis. Colour Doppler sonography showed only peripheral but no intralesional flow. Since the lesion was presumed as malignancy bilateral high inguinal orchiectomy was performed and bilateral idiopathic granulomatous orchitis was diagnosed. It was concluded that granulomatous orchitis should be considered in the differential diagnosis of diffuse testicular hypoechoic involvement which showed only peripheral low-resistance flow on colour Doppler sonography, in the proper clinical setting. Although this may be a helpful sign in the differential diagnosis of diffuse testicular infiltrations, high inguinal exploration remains mandatory.
In the management of infertility, in case semen quality is found insufficient and could not be improved by medical means, handling the available spermatozoa in the most beneficial way has been aimed. Thus, artificial insemination with low quality semen has become a therapeutic alternative. In this study homologous artificial insemination has been used to treat infertility caused by oligoasthenospermia. Eighteen couples have been treated for 58 cycles by intrauterine or paracervical insemination using cervical cups. During the same period 42 cycles with timed vaginal intercourse have been assessed. Though no pregnancies could be obtained following artificial insemination, one pregnancy occurred during no-treatment cycles.
We have treated 45 patients with various degrees of oligospermia and asthenospermia with arginine, indomethacin and kallikrein. Fifteen patients have received the amino acid L-arginine hydrochloride, 15 the antiinflammatory agent indomethacin, while 15 others the enzyme kallikrein. These drugs have been administered for at least 3 months to encompass a complete cycle of spermatogenesis. As a result, treatment with these drugs has increased sperm count and motility to some extent. Three pregnancies (20%) have been obtained by arginine and one pregnancy (6.6%) by indomethacin. Though arginine offers some hope for the future, improvement of the fertilizing capacity with these drugs is still controversial.
Spinal cord injury, regardless of its level, causes flaccid paralysis during the shock phase affecting the detrusor and rectal musculature. Then, depending on the level and severity of the lesion, the bladder gains spasticity or remains flaccid. Monitoring the reflex behaviour of detrusor and sphincter activities helps to select the treatment modalities. Thirty patients with cord injuries of various levels have been urodynamically tested at 3-month intervals. The shock phase of the acutely tested patients lasted about 8-9 weeks. Eventually, 23 of the cases were hyperreflexic, while 7 cases remained areflexic: 2 had detrusor-sphincter dyssynergia. The response to treatment has been investigated by cystometrographical and electromyographical methods.
During a 6-year period 390 patients with urinary tract calculus were studied: 293 had upper and 38 had lower urinary tract calculi. Of these, 59 passed their stones spontaneously on conservative therapy, 294 were treated surgically and 37 stones were removed by endoscopic means. Of the patients 10.54% had a history of urolithiasis, 5.34% reported family history. In contrast to the common belief, the highest admission rate was in winter. The male to female ratio was found to be 2.2:1, whereas it was equal (1:1) in childhood. The peak incidence was between the ages 30 and 39. Urinary tract infection and obstruction of varying severity were the common coexisting abnormalities. Calcium was the main component of both the upper and lower tract stones. Calcium oxalate+phosphate and calcium oxalate+struvite were the most common mixed stones. Blood typing did not reveal any specificity for urinary calculous disease. On the other hand, occupational groups leading a sedentary life were more prone to this malady.
